Triptorelin is a man-made form of a hormone that regulates many processes in the body. Triptorelin overstimulates the body's own production of certain hormones, which causes that production to shut down temporarily.

Triptorelin is used to treat the symptoms of prostate cancer. Triptorelin treats only the symptoms of prostate cancer and does not treat the cancer itself. Use any other medications your doctor has prescribed to best treat your condition.

Triptorelin may also be used for other purposes not listed in this medication guide.

After your injection, your prostate cancer symptoms may get worse for a short time because triptorelin raises your testosterone levels. These side effects should get better within 3 or 4 weeks. Call your doctor if your symptoms do not improve, or if they get worse while using triptorelin.

Some of the side effects of triptorelin are symptoms of prostate cancer that may occur because the medicine raises your testosterone levels. Call your doctor at once if you have pain or burning when you urinate, blood in your urine, bone pain, numbness, tingling, muscle weakness, or loss of movement in any part of your body.

Although triptorelin is not for use by women, this medication can cause birth defects and should not be used by a woman who is pregnant or who may become pregnant.
